ABSTRACT
Objective:
To study the effects of glucose,mannose and galactose on CAP10 promoter activity of Cryptococcus neoformans capsule-associated gene.Methods:
Yeast cells were transfected with plasmid containing a 951 bp length of 5′ upstream flanking sequence of CAP10 coding region and a reporter gene,chloramphenicol acetyl transferase(CAT);the transfectants were treated with different concentrations(10,20,40,60,80 mg/ml) of glucose,mannose and galactose.CAT activity was assessed by ELISA method and CAT activities of different groups were compared.Results:
Different concentrations of glucose and mannose had no obvious influence on CAT activity;different concentrations of galactose had obvious influence on CAT activity and the influence was positively dependent with its dose within the experimental concentration range.Conclusion:
Glucose and mannose have no obvious effect on the activity of CAP10 promoter;galactose has obvious inductive effect on activity of CAP10 promoter,suggesting that CAP10 gene might be related with galactose metabolism.
